,3 Claims; (Cl.248-54) This invention relates to spring hangers and more especially to one particularly adapted for supporting steam pipes and the like in commercial and industrial plants where strength, durability and safety are important factors, and which receive primary consideration in such hangers:

labor, due to its instant adjustability, and its simple and practical construction, which, coupled with its low manufacture and production cost, has rendered it a most --desirable and economical improvement in the plumbing and steamfitting trade.

With the foregoing described and other objects and advantages to be attained as-will hereinafter appear, the inventionconsists in the parts and novel construction and arrangement-thereof as hereinafter described and "set forth in the appended claims.

A clear example of the practical operation of the lower Now, in

our improved spring hanger for steam pipes and the like may be had from reference to the drawings indetail, referring first to Figures 1, 2, 3 and 4 in which are designated generally by numerals the upper yoke H), the lower yoke H, the frame unit :l'2, the tie-sleeve I3 and the plate unit 14.

The substantially U-shaped upper yoke member l0, being adapted for inverted position in assembly, has the threaded portions H)" which slidably engage the apertures [2B in the upper plate portion I2A of the frame unit I2, to extend thence downwardly and threadably engage the upper hexagonally-shaped portion of the tiesleeves l3 (which sl-idably engage the apertures 12D in the lower plate portion l2C'of the frame unit i2), and finally engage by slip-fit the apertures 14A in the upwardly extending boss portions 4B of the plate unit H, the lower end of said threaded portions I'll threadably engaging the nut members l5 whichbear against the bottom faceof the plate unit M to support it, in assembly.

In right-angularly disposed co-operative action and association with the upper yoke member I0 is the substantially U-shaped-though somewhat wider lower yoke member H having the threaded portions ll, said threaded portions l l of the yoke member H and the threaded portions l 0' of the yoke member ID being adapted to face each other in assembly, in that the threaded portions H extend upwardly and slidably through the apertures MB in the plate unit it and into slipfit through engagement with the apertures l-ZE in the spacer sleeve portions [2F of the frame unit 12 to be secured in such engagement by the nut members It threadably engaging the upper end of the threaded portions H of said yoke member I l said nut members it bearing against the upper face of frame-unit I2.

The helical spring I! is mounted between the opposing faces of the lower plate portion I20 of the frame unit 12 and the plate unit 14, being held 'therebetween and secure against lateral movement by means of the spaced apart threaded portions 1 0' of the yoke member ID positioned inwardly of the helical spring and by the spaced apart threaded portions l I positioned outwardly of said helical spring I! and right-angularly arranged with respect to said threaded portions l0, thus forming a resilient cushion for a pipe or pipes resting in the crotch 1 IA of the yoke member I-l"i-n-.use.

*It is obvious too, that ,ini hanging a group of parallelly arranged pipes, the bulk of which would be too large to enter the said crotch IIA, a pair of pipes in our improved spring hangers may be suspended in alignment laterally of the group of pipes, with a cross-bar spanning the pair of hangers by resting in said crotch HA of each hanger, and the group of pipes resting on said cross bar.

In actual use our improved spring hanger is suitably suspended by the inverted crotch 10B of the yoke member H), the pipe or pipes being cradled in the crotch HA of the yoke member I I. It is obvious that in order to adjust the level at which the pipe may be suspended, it is necessary only to move the nut members it either upwardly or downwardly on the threaded portions ll of the yoke member II, and then move the nut members I upwardly on the threaded portions ID of the yoke member ID, thus compressing the helical spring I! between the opposing faces of the lower plate portion [2C of the frame unit 12 and the plate unit 14,

to fix the degree of resiliency desired, and at suitable level. a

It is also pointed out as obvious that the frame unit H in the structure and arrangement shown and described is cushioned on the helical spring I! which is supported on the plate unit [4, and that the frame unit [2 slidably and vertically engages the said threaded portions II and the threaded portions In (within the tie-sleeves l3) to effect such resiliency.

Now, in the event that it becomes necessary to remove the helical spring I! for any reason, it is necessary only to move the tie-sleeves [3 upwardly on said threaded portions ID to contact the lower face of the upper plate portion [2A of said frame unit l2, thus sustaining the position of the frame unit, while the nut members l5 are removed from the lower ends of the threaded portions which releases the plate unit 14 and permits the removal and replacement of the helical spring and at the same time holds the pipe load in its original position until the re-assembly operation is next completed, after which the tie-sleeves l3 are moved downwardly to their original posiiton, resulting in the accomplishment of the original position of the invention as a whole.

From the foregoing it is apparent that a very convenient, practical, and eificient spring hanger is produced, capable of easy adjustment and r manipulation in use, and although the illustrated structure is a practical working embodiment of the invention, it is not a specific limitation, as modification and change is both possible and contemplated within the scope of the appended claims.

What is claimed is: 1. In a spring hanger of the type herein described comprising in combination a pair of op-- posedly facing substantially U-shaped threaded yoke members, a hollow frame unit and a plate unit slidably and co-operatively engaging said pair of yoke members, tie sleeve members mounted on said hollow frame unit and threadably engaging one of said yoke members, a helical spring member mounted between the lower face of said frame unit and the upper face of said plate unit and co operatively there held against lateral displacement by means of one of said yoke members being positioned inside of the spring member and the other yoke member being positioned outside of the spring member.

2.
